Do you by chance know the type of adders used in microcontrollers such as Atmega and PIC? I looked through the datasheets but this is not something they specify.

The manufacturers are very proprietary about there implementations. What's in the data sheets is generally all you can get.

I remember reading that Intel's first 8-bit processor, the 8008 released in the early 1970s, used Carry Lookahead in its ALU.
